Please remove if useless.

Can you please try to clarify this code?
After some oral discussion, it's still not completely clear to me ^^.

If you don't find a way to improve on this, please, at least, add some comments to try and explain it.

Thanks a bunch.

Remove print please.

It'd be nice to have a developer exception here when the docstring is missing.

Something like for example (feel free to adapt ^^):

if not f.__doc__:
    raise Exception('Apidoc %s: expected a docstring'
                    ' for function %s'
                    % (self.__class__.__name__, f.__name__))
